Anthurium plant named ‘ANTHEUDAM’

ABSTRACT

A new Anthurium plant named ‘ANTHEUDAM’ particularly distinguished by having large, shiny and strongly blistered, bright red, cordate and very durable spathes that retain the original color for a very long period of time, dark, elliptical cordate durable leaves, white spadix with yellow-orange tips, early and rich flowering continuously through the year, and a plant height of 45.0 cm to 50.0 cm is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHEUDAM’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘ANTHEUDAM’. The new Anthurium plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, the Netherlands. The objective of this breeding program was to create a new 45.0 cm to 50.0 cm height plant with large, shiny and strongly blistered, bright red, cordate and durable spathes.

The new variety originated from a cross-pollination made in November 2008 in Bleiswijk, The Netherlands. The female parent was a red Anthurium pot plant designated ‘10520-01’ (unpatented), and the male parent was a red Anthurium pot plant designated ‘9863-01’ (unpatented).

A single plant was selected from the progeny of the stated cross in September 2010 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a 7-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in the European Union on Nov. 24, 2015. ‘ANTHEUDAM’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands:

-   -   1) Large, shiny, strongly blistered, bright red and cordate         spathe;     -   2) White spadix with yellow-orange tip; and     -   3) Green, elliptical cordate leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 52-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in June 2017. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 2 shows a close-up of the mature spathe.

FIG. 3 shows a close-up of the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHEUDAM’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 52-week old plants which were planted from tissue culture in 17 centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in June 2017. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2015).
